Enable "SSM (n < nx) with hysteresis and filtering" (p9501.16 = 1) here.
You can enter the filter time for the SSM feedback to detect standstill (n < nx) (p9545)
here.
You can enter a value for the velocity hysteresis for the SSM feedback to detect
standstill (p9547) here.
You can enter the velocity limit for the SSM feedback to detect standstill (p9546) here.
You can set how SSM and its feedback behave during pulse suppression in
encoderless operation (p9509.0).
